React ships with all the features you need to handle your state without a single additional library. Most of your application’s states should not be global as they live just fine in a useState or useReducer or custom hook next to your components. Although react provides why redux us with the state property but passing the state from component A to component B can be quite complex when the application grows. Without Redux, you would need some other event system or have to instantiate the snackbar component every time it gets used.
You can store any data you want in these compartments, and it can hold various kinds of data, such as strings, numbers, arrays, objects, and even functions. The dashboard includes a set of widgets and provides users a lot of options to customize them. A user will adjust widgets according to their needs and the app state will change based on the user input. You can rest assured that React Redux is always up-to-date, adheres to the design best practices of React, and creates a helpful abstraction layer between components of your app and the Redux store. I’ve read about redux but I think redux is not suitable for every app and use case and I should not store single-use responses to redux.
Understanding Redux: A tutorial with examples
You may have noticed that when describing the React Context API, we needed to wrap our content in a Consumer component, then pass a function as a child so that we could access or consume our state. If you happen to be a beginner, it will be a sensible choice to go for Redux. However, it will not always be required to manage your application’s state. While it is used mostly as a state management tool with ReactJS development services, it can be used with other JavaScript libraries or frameworks. Furthermore, at 2KB, it is lightweight, and therefore, there is no need for you to be concerned about it making the asset size of your application larger.
It depends on the developer’s capabilities and I can care about encapsulation as much as I want. Once you have installed the needed dependencies, create a new «slice» using the createSlice function. A slice is a portion of the Redux store that is responsible for managing a specific piece of state. You now have a good grasp of how to integrate Redux into your React applications.
When should I use Redux in my react application?
To use Redux Thunk, you need to install it as a dependency and apply it to your Redux store using the applyMiddleware function. It’s more opinionated with its predictable way https://deveducation.com/ of managing state, both a plus and a minus depending on your needs. The lack of flexibility might help prevent bugs, but could also be a disadvantage in certain situations.
Essentially, the React Context API is React’s way of managing state in multiple components that are not directly connected. To handle data between disconnected components in React, developers use prop drilling. Then, we create a store object by calling configureStore and passing it an object with a reducer property. The reducer property is an object that maps reducer slice names to their corresponding reducer functions. In this case, we have one reducer slice called todo, and its corresponding reducer function is todoReducer.
This helps you restrict any part of the view or any network calls to write/update the state directly. And firing the action of adding one item to the cart again will increase the number of items in the cart to 2. «Actions can be recorded and replayed later, so this makes state management predictable. With the same actions in the same order, you’re going to end up in the same state.»
In the same way, when you create a Redux Store you do a similar kind of initial deposit which is known as initialState. We will represent this initialState as a second argument passed into the createStore. State management is a big concern in large applications and Redux solves this problem. Some nice things you can do with Redux are logging, hot reloading, time travel, universal apps, recording, replay, etc. Context API is very specific to the react-redux part on how React components are connected to the store. But if you want to, since Context is officially supported, you could use the Context API instead of react-redux.
